-/**
- * waitForPath efficiently implements waiting for the existence of a path.
- *
- * We intentionally do not use fs.watchFile as it is very slow from testing.
- * I believe it polls instead of watching.
- *
- * The way this works is for each level of the path it will check if it exists
- * and if not, it will wait for it. e.g. if the path is /home/nhooyr/.config/coder-cloud/session
- * then first it will check if /home exists, then /home/nhooyr and so on.
- *
- * The wait works by first creating a watch promise for the p segment.
- * We call fs.watch on the dirname of the p segment. When the dirname has a change,
- * we check if the p segment exists and if it does, we resolve the watch promise.
- * On any error or the watcher being closed, we reject the watch promise.
- *
- * Once that promise is setup, we check if the p segment exists with fs.exists
- * and if it does, we close the watcher and return.
- *
- * Now we race the watch promise and a 2000ms delay promise. Once the race
- * is complete, we close the watcher.
- *
- * If the watch promise was the one to resolve, we return.
- * Otherwise we setup the watch promise again and retry.
- *
- * This combination of polling and watching is very reliable and efficient.
